Not really. The point of a government is to be the big intimidating force that keeps would-be exploitative forces in check, but it's now owned and run by those very people. The second amendment was made for this exact scenario, because when the big brother protecting you from bullies becomes a bully, the only one left to put up a fight is you.

I have bad news: real way is to stop producing humans like what we have now in the upper class. Unless this is done, best we can get is a periodic cleansing, until next time of "well, things went to shit again"

You've isolated the crux of the issue. Those in power have long since realized that they can abuse your trust to 2 ends - they can exploit you while you trust them, and even when you stop trusting them, you tend to stop trusting everyone, making it harder for you to come together with your peers to rival the strength of the system.

The paradox we must overcome is that we must inherently distrust the wealthy, while still having enough trust in our peers to stand with them against the wealthy without fearing that they'll shoot us in the back. It seems easy to differentiate between the two groups, but it's surprisingly difficult to see 2 people with no outward differentiating factors, yet trust one with your life and assume the other is planning to manipulate you.
